We all know how important sleep is, but many of us struggle to consistently get enough high-quality rest. This book answers readers' sleep-related questions and offers guidance for a better night's slumber.

Part of Bloomsbury's Q&A Health Guides series, this book aims to educate teens and young adults about the importance of sleep through an engaging question-and-answer format. The book's 44 questions cover the basics of sleep and dreaming, the connection between sleep and health, sleep problems and disorders, and how to improve sleep:
- Why exactly is sleep so important?
- How does not getting enough impact physical wellbeing, academic performance, and interactions with others?
- How do you know if you have a sleep disorder?
- Can caffeine and power naps really make up for poor sleep habits?

The text strikes a balance between theory and practice, offering both clear explanations of foundational concepts in sleep science and useful suggestions that readers can implement in their own lives.

Augmenting the main text, a collection of 5 case studies illustrate key concepts and issues through relatable stories and insightful recommendations. The "Common Misconceptions" section at the beginning of the volume dispels 5 long-standing myths about sleep, directing readers to additional information in the text. The glossary defines terms that may be unfamiliar to readers, while a directory of resources curates a list of the most useful sleep-related books, websites, and other materials. Finally, whether they're looking for more information about sleep or any other health-related topic, readers can turn to the "Guide to Health Literacy" section for practical tools and strategies for finding, evaluating, and using credible sources of health information both on and off the Internet.
